Title: Chain tensioner
Inventor: POIRET CHRISTIAN
IPC: F16H7/08
Filed: 1991-09-14
Abstract: A chain tensioner has a support member 1 and a pressure applying member 4 mounted thereon. Biassing means 5 act to cause the support member to change position so as to increase tension on the chain if the chain tension slackens. Means 2, 9 prevent return movement of the support member when the chain tension increases. The pressure applying member 5 is moveable relative to the support member 1 in response to variations in tension in the chain and at least its movement towards the support member is damped. As shown the pressure applying member comprises a slipper head 4 biassed away from the support member by a V-shaped steel spring 6. A spacer 8 provided additional resilient damping. <IMAGE>

Title: Cigarette magazine
Inventor: FOCKE HEINZ
IPC: B65B19/04
Filed: 1991-10-22
Abstract: A cigarette magazine serves for receiving a small supply of cigarettes (10) and for forming cigarette groups which correspond to the contents of a cigarette pack. For this purpose, the cigarettes (10) are guided into upright magazine shafts (14) in which cigarette rows (15) of superposed cigarettes are formed. The cigarettes (10) are downwardly conveyed in the magazine shafts (14) under gravity. In this process there may occur problems, especially with cigarettes (10) having a filter (29). To ensure a faultless transport, the shaft walls (16) for defining the magazine shafts (14) are designed with a smaller width, such that the filters (29) of the cigarettes (10) are located beyond the region of the shaft walls (16). In a lower region (30) where the cigarettes are pushed out in groups by a reciprocating slider (28), the shaft walls are extended to at least the length of the cigarettes. <IMAGE>
